Resource efficient method for reuse of chemical sludge
The project aims to further develop a method for recovering precipitation chemicals (iron and aluminum) from sludge arising from the purification of drinking water. A patented method recovers the precipitation chemical and the remainder of the sludge becomes combustible coal. The project has the potential to contribute to the elimination of the waste flow of chemical sludge, while at the same time reducing the need for energy and resource demanding new chemical production.
